Somehow, I see paragraph 2 differently.

Spoiler for paragraph 2

I see paragraph 2 this way:
weight = rope + 2*(2*3*3a - 1.125a) -2.25a

 

Spoiler for One approach

When the narrative says "was when," or "will be when,"
denote that time frame by an offset of a, b, c, d ... years.

So "... monkey was years old when (x-a) mother was (y-a)
twice as old as brother was when (z-b) mother was (y-b)
half as old as brother will be when (z-c) brother is (z-c)
three times as old as mother was when (y-d) mother was (y-d)
three times as old as monkey was (x) in paragraph 1.

This says

y-a = 2(z-b)
y-b = (z-c)/2
z-c = 3(y-d)
y-d = 3x

The whole paragraph says W = L/4 + (x-a).

Eliminate a, b, c, d, and use z = (x+y)/2.

That's not what paragraph 2 says in the OP.

 

You're right. OP is corrected.

I was presumptuous to teach you how to solve ...

Apologies.

Thanks. That brings it closer. I get a positive weight rope now, alas, not enough for the monkey and the rope together to balance the weight.

Spoiler for paragraph 2

The way I see paragraph 2 now:
Weight - rope = ((3*3a)/2 -1.125a)*2 - 2.25a = 4.5a. (Where a=16/17).

Whereas, Weight + rope = 4.875a (from paragraph 1). Leaving the weights as 0.1875a for the rope weight, 4.6875a for the weight, and 3.25a for the monkey. Where the monkey together with the entire rope cannot outweigh the weight.

Spoiler for is Russian translation available?

If "...the weight of the weight and the weight of the rope were together half as much again as the weight of the monkey," how can that system be in equilibrium?

 Конечно ...   Веревка подбежал шкив, на одном конце была обезьяна, на другом конце вес.Два оставшихся в равновесии.Вес каната было 4 унции / футбол, а в возрасте от обезьяны и мать обезьяны составил четыре года.Вес обезьяна была много фунтов, как мать обезьяны было лет, и весом весом и весом каната вместе были в полтора раза больше, поскольку вес обезьян.
 
Вес вес превышал вес веревки, как многие фунтов, как обезьяна лет, когда мать обезьяны был вдвое старше брата обезьяны было, когда мать обезьяны был вдвое старше брата обезьяна будет, когда брат обезьяны в три раза стара, как мать обезьяны Когда мама была обезьяна была в три раза стара, как обезьяна в пункте 1.
 
Мать обезьяны был вдвое старше обезьяна Когда мать обезьяны был наполовину стара, как обезьяна будет Когда обезьяна в три раза стара, как мать обезьяны было, когда мать обезьяны в три раза стара, как обезьяна в пункте 1.
 
Возраст матери обезьяны превысил возраст брата обезьяны на такую ​​же сумму, как возраст брата обезьяны превысил возраст обезьяны.
 
Какова была длина веревки?

       So the rope has legs and plays footbal?! And monkey's mother is a male?! And age is money?!Was it Google translation? I guess, it'll be awhile before computers can understand and translate natural language.Although it's worth noting that about the only bit translated correctly, is that very thing, which I misunderstood. The translation states, the weight of the rope together with the weight is 1.5 times the weight of the monkey, as the problem statement intended. Whereas I understood it as half weight of the monkey.

I was going to add the caveat that I cannot verify the usefulness of google translate. But yes, I thought all monkeys played football.

Actually now I am convinced the puzzle is broken in paragraph 2.
Trying to fix it, knowing the answer, but I may just close the topic.

Thanks for working on it.
